A 1.04 g sample of KBr is dissolved in water to give 155 mL of
solution. This solution is then added to 165 mL of 0.015 M aqueous
Pb(NO3)2, in an attempt to remove the toxic lead(II) ions from the
solution via precipitation as insoluble PbBr2(s).
The precipitation reaction that occurs is: Pb2+ (aq) + 2 Br (aq)
---> PbBr2 (s)
